Abstract
A method and system are provided for adapting a vehicle control strategy of an on-road vehicle following a reoccurring fixed route to a predetermined destination, which fixed route extends through at least one geographical zone associated with at least one environmental restriction. When it is determined that the vehicle is approaching the geographical zone, historical data collected from previous passages of one or several vehicles through the zone is accessed, and the vehicle control strategy inside the geographical zone is adapted based on the historical data and the environmental restriction.
Claims19
A method for adapting a vehicle control strategy of an on-road vehicle following a reoccurring fixed route to a predetermined destination, the fixed route extending through at least one geographical zone defined to have at least one environmental restriction, the method comprising:
- determining that the V chicle is approaching one of the at least one geographical zone,
- verifying that passage through the zone while complying with the environmental restrictions is possible,
- accessing a database to acquire historical data collected from previous passages a one or several vehicles through the at least one geographical the zone, wherein the historical data is tagged based on at least one time related parameter,
- selecting relevant historical data from the database based on a current or forecasted condition of the time related parameter, and
- adapting the vehicle control strategy inside the at least one geographical zone based on the historical data and the environmental restriction, wherein the vehicle control strategy is provided to set at least one operating parameter to control the operation of the vehicle and the operating parameter is a drive mode for the vehicle, allowing the vehicle to select electric or combustion engine propulsion,
- wherein the historical data includes at least energy consumption and required time of passage, and wherein adapting the vehicle control strategy includes adapting the at least one operating parameter for optimizing energy consumption of the vehicle.
An on-hoard system for adapting a vehicle control strategy of an on-road vehicle following a reoccurring fixed route to a predetermined destination, the fixed route extending through the at least one geographical zone defined to have at least one environmental restriction, the system comprising:
- a positioning unit for determining when the vehicle is approaching one of the at least one geographical zone based on a determined position of the vehicle, and
- a control unit configured to:
- verify that passage through the at least one geographical zone while complying with the environmental restrictions is possible
- access a database for historical data collected from previous passages of the at least one vehicle through the at least one geographical zone, wherein the historical data is tagged based on at least one time related parameter,
- select relevant historical data from the database based on a current or forecasted condition of the tune related parameter, and
- adapt the vehicle control strategy inside the geographical zone based on the historical data and the environmental restriction, wherein the vehicle control strategy is provided to set at least one operating parameter to control the operation of the vehicle and the operating parameter is a drive mode for the vehicle, allowing the vehicle to select electric or combustion engine propulsion,
- wherein the historical data includes at least energy consumption and required time of passage, and wherein adapting the vehicle control strategy includes adapting the at least one operating parameter for optimizing energy consumption of the vehicle.
